Description

An overhead view of the same glacier with outlines marking changes in its areal extent.

A 1981 aerial photograph of Grinnell Glacier in Glacier National Park with indications of the approximate former extent of the glacier. This glacier has retreated from a total extent of ~2.3 square kilometers circa 1850 to ~1.1 square kilometers in 1993, and is now distributed in two major and five minor segments. [1] Like other glaciers in Glacier National Park, it is predicted that Grinnell Glacier will disappear by 2030 under current projections for the rate and extent of global warming (Hall 1994).
